Cinderbid turns plan sets into priced, defensible bids for enterprise general contractors and owners — with calibrated accuracy metrics, a full audit trail on every number, and deployment on your own infrastructure.
From ingest to sealed bid, every stage runs under verification gates — so estimating stops being a bottleneck and starts being an audited system of record.
Layout-aware vector PDF takeoff runs locally in the browser via WebGL — zero-leakage by design. Plans, specs, and drawings are parsed into structured scope and quantities without leaving your environment.
Monte Carlo simulation over regional cost data produces priced estimates with explicit uncertainty bands, margin floors, and volatility alerts — numbers your review board can interrogate.
Independent verification re-checks every quantity and price before release. Gated bid revisions mean no estimate ships without passing its checks, and every override is recorded.
Usage runs against a prepaid Cinderblock ledger with idempotent transactions and a locked retainer reserve — predictable spend, no surprise invoices, every charge reconciled.
We publish our calibration instead of hiding it. Cinderbid's historical accuracy is measured against real bid outcomes with leave-one-out validation, and every estimate carries a trace: inputs, model passes, verification checks, and revision history — exportable for compliance review.
Pull opportunities and compliance data straight from the sources your capture team already watches — on our managed network or with your own API keys.
